Tax-free Internet shopping in jeopardy

Tax-free shopping on the Internet could be jeopardized by a bill making its way through the Senate.

The bill would empower states to require online retailers to collect state and local sales taxes for purchases made over the Internet. The sales taxes would be sent to the states where a shopper lives.

Under current law, states can require stores only to collect sales taxes if the store has a physical presence in the state. As a result, many online sales are essentially tax-free, giving Internet retailers a big advantage over brick-and-mortar stores.

The Senate voted 74 to 20 Monday to take up the bill. If that level of support continues, the Senate could pass the bill as early as this week.

Supporters say the bill is about fairness for businesses and lost revenue for states. Opponents say it would impose complicated regulations on retailers and doesn't have enough protections for small businesses. Businesses with less than $1 million a year in online sales would be exempt.
